that this requires a (stable) reference clock (32 kHz
RTC clock or CFG_8XX_XIN)
+- Intel Monahans options:
+ CFG_MONAHANS_RUN_MODE_OSC_RATIO
+
+ Defines the Monahans run mode to oscillator
+ ratio. Valid values are 8, 16, 24, 31. The core
+ frequency is this value multiplied by 13 MHz.
+
+ CFG_MONAHANS_TURBO_RUN_MODE_RATIO
+
+ Defines the Monahans turbo mode to oscillator
+ ratio. Valid values are 1 (default if undefined) and
+ 2. The core frequency as calculated above is multiplied
+ by this value.
+
- Linux Kernel Interface:
CONFIG_CLOCKS_IN_MHZ
The maximum size of the constructed OF tree.
OF_CPU - The proper name of the cpus node.
+ OF_SOC - The proper name of the soc node.
OF_TBCLK - The timebase frequency.
+ OF_STDOUT_PATH - The path to the console device
+
+ CONFIG_OF_HAS_BD_T
+
+ The resulting flat device tree will have a copy of the bd_t.
+ Space should be pre-allocated in the dts for the bd_t.
+
+ CONFIG_OF_HAS_UBOOT_ENV
+
+ The resulting flat device tree will have a copy of u-boot's
+ environment variables
+
+ CONFIG_OF_BOARD_SETUP
+
+ Board code has addition modification that it wants to make
+ to the flat device tree before handing it off to the kernel
- Serial Ports:
CFG_PL010_SERIAL
CFG_CMD_DIAG * Diagnostics
CFG_CMD_DOC * Disk-On-Chip Support
CFG_CMD_DTT * Digital Therm and Thermostat
- CFG_CMD_ECHO * echo arguments
+ CFG_CMD_ECHO echo arguments
CFG_CMD_EEPROM * EEPROM read/write support
CFG_CMD_ELF * bootelf, bootvx
CFG_CMD_ENV saveenv
- CFG_MALLOC_LEN:
Size of DRAM reserved for malloc() use.
+ - CFG_BOOTM_LEN:
+ Normally compressed uImages are limited to an
+ uncompressed size of 8 MBytes. If this is not enough,
+ you can define CFG_BOOTM_LEN in your board config file
+ to adjust this setting to your needs.
+
- CFG_BOOTMAPSZ:
Maximum size of memory mapped by the startup code of
the Linux kernel; all data that must be processed by
These two #defines specify the offset and size of the environment
area within the first NAND device.
+ - CFG_ENV_OFFSET_REDUND
+
+ This setting describes a second storage area of CFG_ENV_SIZE
+ size used to hold a redundant copy of the environment data,
+ so that there is a valid backup copy in case there is a
+ power failure during a "saveenv" operation.
+
+ Note: CFG_ENV_OFFSET and CFG_ENV_OFFSET_REDUND must be aligned
+ to a block boundary, and CFG_ENV_SIZE must be a multiple of
+ the NAND devices block size.
+
- CFG_SPI_INIT_OFFSET
Defines offset to the initial SPI buffer area in DPRAM. The
